Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493566, here are decompositions:

47 + 31493519 = 31493566
53 + 31493513 = 31493566
89 + 31493477 = 31493566
227 + 31493339 = 31493566
317 + 31493249 = 31493566
509 + 31493057 = 31493566
557 + 31493009 = 31493566
569 + 31492997 = 31493566

Showing the first eight; more decompositions exist.
